Plain white silica gel with the broadest mesh range in the catalogue and the highest published loading at high humidity.
Bulk Silica Gel
Highest published adsorption — ≥70% at 90% RH
Where no visual indicator is needed, non-indicating white gel is the workhorse. It carries the widest published size range of any grade here — eight mesh classes and thirteen particle-size options — and the strongest high-humidity loading figure, making it the default choice for sachet filling and bulk process drying.

Custom sizes are routine. If none of the standard weights suit your enclosure, tell us the dimensions and we will quote an odd size, a different pouch material, or printed pouches to your artwork.
